New insights into mechanisms of enhanced synaesthetic memory: Benefits are synaesthesia-type-specific

The goal of this study was to test the nature of the memory advantage in synaesthesia. We compared four different types of synaesthetes (27 grapheme-colour, 21 sound-colour-, 25 grapheme-colour-and-sound-colour- and 24 sequence-space synaesthetes) to their matched controls. Recognition memory for th...

description The goal of this study was to test the nature of the memory advantage in synaesthesia. We compared four different types of synaesthetes (27 grapheme-colour, 21 sound-colour-, 25 grapheme-colour-and-sound-colour- and 24 sequence-space synaesthetes) to their matched controls. Recognition memory for three types of stimuli (music, words, colour) was tested. We anticipated a general advantage in memory for synaesthetes and potentially additional synaesthesia-specific benefits. The results showed a general advantage for synaesthesia. Further, a benefit for colour stimuli resulted for grapheme-colour synaesthetes and a benefit for music stimuli resulted for grapheme-colour-and-sound-colour synaesthetes, indicating synaesthesia-type specific effects. These results suggest different mechanisms for the explanation of the memory benefit for different types of synaesthesia such as synaesthesia-related colour expertise for grapheme-colour synaesthesia and additional encoding opportunities for grapheme-colour-and-sound-colour synaesthesia.
